I dunno, I always recomment just switching over to Expression Mode (and staying there).

this may seem stupid but where do I go to create local variables? in the interface builder there is a section for local variables but there is no add button.

Here's a quick example of how I would structure this - this only has 2 initial values but can be scaled to pretty much as many as you want.

a!localVariables(
  local!item1: 0,
  local!item2: 0,
  
  local!total: local!item1 + local!item2,
  
  a!formLayout(
    label: "Addition example",
    contents: {
      a!textField(
        label: "Value 1:",
        value: local!item1,
        required: true(),
        saveInto: {a!save(local!item1, tointeger(save!value))}
      ),
      a!textField(
        label: "Value 2:",
        value: local!item2,
        required: true(),
        saveInto: a!save(local!item2, tointeger(save!value))
      ),
      a!textField(
        label: "Totals:",
        readOnly: true(),
        value: local!total
      )
    },
    buttons: a!buttonLayout(
      primaryButtons: {
        a!buttonWidget(
          label: "Submit",
          saveInto: {
            a!save(
              ri!evaluatedTotal,
              local!total
            )
          }
        )
      }
    )
  )
)

Hi Mike,

I was charged by my organization to evaluate Appian. I have created a form where employees submit a training request including the cost of the training. I have a section for inputting the cost with 4 decimal fields(tuition cost, living cost….etc) to input the financial information and 1 field to save the total of the cost. It is all part of an approval process where the employee submit the form a manager recommend it and finally an executive will approve it. I need help to saving the total cost in a Totalcost field.

Thanks mike for your it is really appreciated.

This depends a bit on the context of what you're trying to do and where/how. Is this a form used on a Task in a running process model? If so, the easiest way I've found to do something like this is to have your Submit button save the calculated value into a Rule Input, passing that value back into the process where you can use it for whatever you were wanting.

Hi Mike,

I was able to display the total amount of the 4 fields in a text field but how can I save the sum of 4 fields in my total fields. In powerApps , you just need to create a calculated field but I don't know how it works in Appian.

Thanks,

The simplest way by far would be to create a 5th text field below the previous 4, and set it to readOnly with a value of "ri!field1 + ri!field2 ..." etc.
